Description
Technical field
The utility model belongs to the technical field of drillhole blasting engineering blanking plug, is specifically related to a kind of quick blocking water filling spalling tubulose perforation plugging device.
Background technology
In drillhole blasting engineering, rational blocking can limit big gun hole cavity implode gas and leak too early, extends stress time in blasthole pressure and rock mass, increases the broken scope of explosion rock mass, improves demolition effect.The composition of blast hole stemming material, packed configuration, stemming length, filling density etc. not only has material impact to the communication process of blanking plug stress wave in big gun hole, and the change to detonation gas pressure in big gun hole, stress field in rock mass, air blast effect, the motion process of choke material in big gun hole, noise of blasting etc. all produce important impact, thus also just directly affect demolition effect and bursting work safety.
The eighties in 20th century rises, start both at home and abroad to pay attention to blast hole stemming problem, as document [2] Zhou Zhiqiang, Yi Jianzheng, Cai Junfeng, Gou Yongqiang. the effect of blast hole stemming thing and progress [J] thereof. explosive, 2009,38(5): 29-33, and carry out a series of researchs such as wad act mechanism, packed configuration, choke material, stemming length, in literary composition, refer to the pluses and minuses of multiple plug structure and various blanking plug.And document [4] Zhao Xintao, Huanghai Sea dragon. affect vertical hole stemming length research [J] of rock blasting quality. highway communication science and technology, 2010,27 (7): 95-98; The new great waves of document [5], Liu Dongyan, Cheng Guihai, Li Dongsheng. the detonation gas mechanism of action and rock crack extensive diagnostic [J]. University Of Chongqing's journal (natural science edition), 2011,34 (6): 75-80; Document [6] Wang Chen, Wen Zhong, Cao Mengyu. in Tunnel Blasting, the effect of stemming and stemming length calculate [J]. mining technique, 2011,11 (5): 118-120 have studied the impact of stemming length on demolition effect from theory into action, give the computational methods of optimum stemming length.Document [7] Luo Wei, Zhu Chuanyun, Zhu Qihu in addition. the numerical analysis [J] of stem length in tunnel photoface exploision. rock-soil mechanics. 2008. 29 (9): 2487-2492; Document [8] Ding Xiping, Wang Zhongqian, Feng Shuyu. stemming length is to the numerical simulation [J] of bench blasting function influence. coal journal, 2001, (4): 370-373; Document [9] yellow Baolong. stone drifting collimating aperture Cut Blasting experimental study [D]. China Mining Univ. (Beijing) .2011, by numerical simulation analysis, compares the stress of key position, obtains optimum stemming length.Document [10] Tang Zhonghua, Zhang Zhi is, Lu Wen, Zhang Shunchao. multiple-row blasting and obstruction method are on the impact [J] of demolition effect. and Xinan Polytechnical College journal .1998.13 (2): 64-66. refer to different obstruction methods and blockage structure to the impact of demolition effect.Up to the present, about the mechanism of action of blast hole stemming, the choke material characteristics of motion, the change of stress distribution and the relation of filling parameter in detonation gas pressure and rock mass, the research of the optimum problem such as stemming length and packed configuration is comprehensive not enough and go deep into, so that in theory still exist not quite identical, or even the viewpoint of opposition.Aborning, choosing usually based on empirical method of blast hole stemming parameter, has sizable limitation, can not adapt to the needs of modern production development.
If big gun hole does not block or stemming length is too short or blockage structure is unreasonable, detonation gas will go out big gun hole in very short time, causes the waste of quick-fried energy, also can produce a large amount of poison gas; If stemming length and blockage structure suitable; due to cohesion and the frictional resistance of tamper inertia resistance and itself and big gun hole inwall; add the duration of HTHP in hole; the crack of previously having been caused by shock wave is fully developed under the gas wedging action of gases at high pressure; catalase so not only can be made more abundant; obtain reasonable demolition effect, and effectively reduce quantity and the casting distance of blasting flyrock, reduce the intensity of air-shock wave; If stemming length is long or blockage structure is improper, will increase blocking amount reduce explosive charge, make explosion volume reduce had a strong impact on explosion progress, may occur when rock blasting door hanging curtain or on cliff stone phenomenon, be worthless.
And in actual production, overview " stemming " kind applied at present of getting up can be summarized as four classes:
1) the solid blocking of loose structure: as rock dust, sand, clay, colloid and their mixture thereof.
Modal in blast working is sand, rock dust, clay and composition thereof, has high-quality, great friction coefficient, plasticity are good, the advantage such as easily to obtain, with low cost, obtains on-the-spot extensive accreditation.But in long-term application, also expose problems: as stemming supply inconvenience, filling operation is various, and labor strength is large, and the activity duration is long, and shutoff difficult quality controls, easily appearance " shooting " phenomenon or explosive miss-fire phenomenon; Can the quality affecting coal etc. problem after mixing with coal; To the type of material and granularity requirements higher, the excessive easy generation slungshot of granularity; After explosion, lumpiness is larger.
For above-mentioned reasons, workpeople, in order to reduce labour intensity, saves man-hour, usually to adopt without plastic sillar, coal cinder, coal dust or powder stick paper as perforation plugging to replace " stemming "; Or clear-cut not sealing clay, adopts the method for large dose to make up the deficiency of perforation plugging, the serious consequence such as consequently cause explosive charge serious waste, country rock is badly damaged, section shaping is poor, accident rate is high.
2) liquid blocking: as the aqueous solution, water stemming material etc.
Water or air realize Uncoincided charge after inserting big gun hole, can weaken detonation pressure peak value, extend detonation gas action time, improve the capacity usage ratio of explosive charge, and water can also be lowered the temperature, depositing dust, fall concussion of blasting, reduce the generation of pernicious gas, be therefore widely used in all kinds of explosion.Water stemming material and air stemming density is little, intensity is low, weak with the friction of big gun hole wall, though be known as stemming, but in fact can not block initialing assault of explosive charge, not play the effect in blocking big gun hole, during use, the soil of certain length, sand or tamper must be clogged at orifice part.
3) mechanical action formula blocking: primary structure has the forms such as end vertebra shape, wedge shape, expanding screw filate, making rapidoprint has plastics, rubber, timber etc.
(1) base cone shape Blast hole plug
The feature of base cone shape Blast hole plug is that certain taper is arranged at bottom, and this kind of Blast hole plug is generally made of plastics, and has strong adaptability, easy to use, low cost and other advantages, but can not be used alone, and needs to add stemming again after filling in.
(2) wedge shape Blast hole plug
Wedge shape expansion combination is modal a kind of Blast hole plug structure, can be made up of plastics, timber or pottery etc., and test proves this kind of Blast hole plug, and when not having precompressed or seal without stemming again, the effect of wedge shape Blast hole plug is very micro-; When having precompressed or have stemming to seal again, action effect is obvious, if but occur blind big gun, be difficult to get rid of.
(3) expanding screw filate Blast hole plug
Expanding screw filate Blast hole plug also uses the principle of wedge shape expansion combination, and the blocking reliability of this kind of Blast hole plug increases than wedge shape Blast hole plug, can be used alone, lower to except hole, inclined hole and lateral aperture except being applicable to, and is also applicable to the filling of upward hole.
4) chemical reaction type blocking: as energy rapid condensation solidification and expansion after the mixing of bi-component organic solution, also have inorganic reaction shaped material, inside add the components such as swelling agent, early strength agent, quick-setting additive, meet water generation fast reaction, consolidation expansion solidifyingization.
As can be seen here, the application of current stemming and safe, efficient, the energy-saving and environmental protection of Modern Pit are exploited very inharmonious, for this reason, are badly in need of research and development a kind of novel " stemming ", make up the deficiency of existing " stemming ", to comply with the demand of Modern Pit development.
